STMicroelectronics STEVAL-CCA012V1

Overview

STEVAL-CCA012V1 from STMicroelectronics is a 3 W filter-free Class-D audio amplifier demonstration board based on the TS2007FC Flip-Chip IC, delivering 1.4 W per channel into 8 Ω at 5 V with ≤1% THD+N, 6/12 dB selectable gain, and 88% typical efficiency. It supports dual-channel operation with independent active-low standby control and is designed for portable audio system evaluation.

For engineers reviewing the STEVAL-CCA012V1 datasheet, STEVAL-CCA012V1 pinout, STEVAL-CCA012V1 application, or STEVAL-CCA012V1 equivalent, key selection criteria include fixed-gain configuration flexibility, low-pop/click startup (<1 ms), thermal and short-circuit protection, and compatibility with 2.4–5.5 V supply rails in space-constrained audio designs.

Technical Context

The board implements the TS2007FC's integrated PWM oscillator (280 kHz base frequency) and H-bridge output stage, enabling filter-free operation by shifting switching energy beyond audible range. Gain selection is controlled via logic-level GS pin, while separate /STBY pins per channel allow independent power gating.

Pop-and-click suppression circuitry ensures <1 ms startup time and minimal transient noise during enable/disable transitions. Protection features include thermal shutdown and output short-circuit detection, both implemented within the TS2007FC die and directly exposed on the board layout.

FAQ

Is STEVAL-CCA012V1 still in production?

No. STEVAL-CCA012V1 is marked as Obsolete in ST's official documentation (Doc ID 15861 Rev 1, June 2009). It remains available through Aetrix Electronics as a legacy evaluation resource with full technical documentation and known design history for backward-compatible prototyping.

Can the gain be changed dynamically during operation?

Yes. The TS2007FC on STEVAL-CCA012V1 supports real-time gain switching between 6 dB and 12 dB via the GS pin, which accepts standard CMOS logic levels. No power cycle or reset is required - transition occurs within one PWM period (~3.6 µs at 280 kHz).

Does the board include input coupling capacitors?

Yes. The schematic shows two 220 nF AC-coupling capacitors (C1, C2) on the differential input path, plus a 1 µF bypass capacitor (C3) on the VCC rail. These are placed per TS2007FC recommendations to block DC offset and suppress supply noise.

What is the purpose of JP1 and JP2 jumpers?

JP1 and JP2 provide physical access to the GS (gain select) and /STBY (standby) control signals for each channel. They allow users to tie these pins to VCC or GND using shunts, enabling manual configuration of gain and channel enable states without soldering or external logic.
